To all whom it may concern.'

Be it known that I, EMIL Kreun, a citizen ofthe United States', and aresident of Livingston, in the county of Essex and State of New Jersey, have invented certain'iiew and useful Improvements in Fluid-Driven Motors, of which the following is a specilication.

The invention rela-tes to motors, more particularly to fluid driven rotary'niotors.

It has for its object to effect by means of a liuid directed to a suitably mounted mass, the rotation of said mass without the use of buckets, blades, and the like heretofore employed, and whereby a smooth action is obtained in that practically -all vibration is eliminated. The motor is particularly suit! able for use in gyroscopic apparatus; and this adaptation thereof is shown in a copending application filed by. mesimultaneously with the present application, but wherein no specific claim is made to the motor itself.

The nature of the invention will be best understood when described in connection with the accompanying drawings, in which- Figure 1 is an elevation, partly in section, of the improved motor; and Fig. 2 is a plan thereof, with a portion of the rotatable or spinning mass broken away.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, 1() designates a suitable base, the upper surface of which is provided with a depression or cavity 11, herein shown as spherical, but which may be bounded by any other surface of revolution. Suitable standards 12 extend upwardly from base 10 and support in bearings 13 a shaft 111 of a rotatable or spinning mass 15, the shaft being provided, for eX- ample, with pulleys 16 from which power may be taken. The periphery of mass 15 1s perfectly smooth and its curvature corresponds to that of the cavity 11 in the present instance, spherical; and the extent of said cavity surface may be varied to suit the different applications of the apparatus, the width of same, however, being preferably less than the width of the wheel. The said mass 15, moreover, is so mounted with respect to the base member 10 as t o leave a passage-way 17 between the periphery of the said rotating mass 'and the surface of cavity 11, that isto say, the radius vof curvature of the former is slightly less than the radius of curvature of the latter, it being understood that the basel member 10 andthe mass 15 are concentrically mounted. The eXact zdifference between the'k ra'dii'forib'est results may be determined bycomputatioii and trial. l Y Iny orderto effect-the rotation of vsaid mass, the actuating fluid (air)v is.; directed thereto, at one side of' the cavity 11 and in the direction ofspin, through a nozzle or duct 20-'pr'eferably` lat.` The' said nozzle is connected with a suitable source (not shown) of air underftlie desired pressure through a pipe 21 communicating with a duct 22in the base 10.

The upper surface of the base 10 Aat the fl'iii'd'end may be inclined, as shown, andthe nozzle 20 formed therein and covered' by means of a' plate Z3 secured thereto; or,'the nozzle may be formed in any other suitable manner. In any case, it terminates substantially at a tangent to the surface of the cavity-11, directly into the same a thin band of the fluid; and of which there will not be an appreciable lateral flaring as it passes through the passage-way 17. By having the coperating portion of the base member 10 entirely below the center of rotation of the spinning mass 15, the fluid, in passing through passageway 17, has the effect of simultaneously counteiacting the weight of the said mass 15 and of imparting its velocity to the same, thereby rendering the apparatus especially suitablefor use asa gyroscope. It is to be noted, also, that the passageway 17 is open throughout to the atmosphere, thus insuring against any reactive forces being set up, and which would be detrimental to the proper action of the spinning mass 15, particularlyshould the same be utilized as a gyroscope.

I claim 1. In apparatus of the character described: a rotatable mass of smooth periphcry; means to support the same having a continuous surface parallel to the periphery of said mass and forming with same, over a portion of same only, a passageway open throughout to the atmosphere; and means to introduce a stream of fluid into said passageway.

2. In apparatus of the character described: a rotatable, spherical mass; a member coperating therewith and having a spherical cavity to provide a passageway; and means to direct a stream of Huid therein.

3. A fluid driven motor, comprising: a suitably mounted rotatable mass having a smooth periphery; a member cooperating with a portion thereof only and of similar curvature to provide a passage-way open throughout to the atmosphere; and means to direct a stream of fluid therein.

4. A fluid driven motor, comprising: a suitably mounted rotatable mass having a smooth periphery; a member cooperating with a portion extending below its center of rotation only and of similar curvature to provide a passage-way open throughout to the atmosphere; and means to direct a stream of fluid therein.

5. A fluid driven motor, comprising: a suitably mounted rotatable mass consisting of a portion of a sphere; a member coperatingV therewith and having a spherical cavity to provide a passage-way; and means to direct a stream of fiuid therein.

6. A uid driven motor; comprising: a base member provided with a spherical cavity; suitable standards extending from said base member; a rotatable mass supported thereby and consisting of a portion of a sphere and fitting concentrically within said cavity to provide a passageway; and means Copies of this patent may be obtained for ve cents each, by addressing the Commissioner Washington, D. G.

to direct a stream of fluid in the said passageway.

7. A fluid driven motor, comprising: a base member provided with a spherical cavity suitable standards extending from said base member; a rotatable mass supported thereby and consisting of a portion of' a sphere; fitting concentrically within said cavity and having a radius of curvature less than that of the said cavity to provide a passage-way; and means to direct a stream of fuid into said passage-way.

8. A fluid driven motor, comprising: a base member provided with a spherical cavity; suitable standards extending from said base member; a shaft mounted on said standards, and power transmitting means thereon; a rotatable mass supported by said shaft and consisting of' a portion of a sphere; fitting concentrically within said cavity and having a radius of curvature less than that of the said cavity to provide a passage-way; and means to direct a band of fluid tangentially into said passage-way.
